A few problems were identified

1) www-data may not be in your sudoers file, check it is present, if not, add the line

www-data ALL=(ALL) NOPASSWD: ALL

to the file.

2) You are missing a "/" from the line "usr/bin/sudo", you should add it to be "/usr/bin/sudo" so the path is correct. usr/bin/sudo does not exist.
